Because a lot of people are stumbling across this issue I will quickly explain how to solve it.

During the installation of the Detlacast 5.19 driver you get an error message related to the driver signature

There are actually two ways to solve the issue.

1. Update your Windows until no further updates are availble (Maybe multiple update cycles are needed). For sure this is not what you want in a production environment because updates can always bring new issues.2. Disable the driver signature enforcement. You can find tons of HowTo's around the web based on your windows version.

But if saveboot is disbaled in your BIOS you can also easily do it on the command line.

“If you are running Windows 7 or Server 2008, the following dialog box may appear mentioning error code 52. It’s due to a Microsoft SHA-1 deprecation policy. Indeed, Microsoft will no longer allow new SHA-1 code signing certificates to be used for signing files on Windows 7 and above starting Jan. 1, 2016. Windows 7 and Server 2008 R2 will require a hotfix for SHA-256 support. Please visit https://technet.microsoft.com/en-us/lib ... ty/3033929 for more information”
